Reddish streaks on skin?

Anyone else get reddish/purplish streaks on their skin with arthritis? My doctor suspects arthritis for all the pain I have, and is running some tests, but I don't have the results yet. I do know I have scoliosis that has pushed my right rib cage out further than the other side and I have lots of pain in lots of places. I was just curious if these streaks I get on my arm and chest could be related. They are comprised of tiny dots...thanks for any info!
